Saab: Buzzing noise

A couple of years ago my 9000 emitted the same buzzing from near the radio
controls. I'm not sure if your 9-3 has the same system, but it was the
sensor for the climate control. Set amongst the cluster next to the
radio,circular grill. My mechanic popped the grill off and removed the unit
which has a small fan. It was loaded with dust and lint. Cleaned it off and
it was fine.

Not sure where this post started,,,,,,,
My '99 9_3 has a buzzing sound coming from the inside right firewall
area, sounds like it comes from above the passengers feet. This
buzzing occurs anytime the engine is brought above 2150rpm, even
sitting still and bringing the engine speed up. I can not hear the
sound from within the engine bay with the hood up and my ear cocked
that direction. It has done this since about ~35k miles.

I have recently noticed that applying the brake stops the buzz, both
while sitting still and while under way. It seems this may have
something to do with vacuam. The buzzing sounds like some sort of
motor that may be running.

Anyone know if there is a vacuam/emmisions motor/pump/valve/whatever
in the passenger firewall area? Car drives fine, the buzzing is
irritating.

Any other 9-3's buzzing around?
